About this file
This solicitation requests proposals for a firm-fixed-price contract to replace the existing high-temperature hot water and steam heating system serving part of Wright-Patterson Air Force Base with new natural gas boilers and supporting infrastructure. The U.S. Army Corps of Engineers Louisville District plans to issue request for proposal W912QR21R0065 to provide new natural gas fired boilers, associated piping, valves, controls and equipment including tie-ins for 22 buildings. Offerors must register in the System for Award Management database and proposals will be evaluated using a best value tradeoff process considering past performance, technical, small business participation, and price factors. The construction magnitude is estimated between $5-10 million and the target ceiling is $8 million. The North American Industry Classification System code is 238220.
